+.Pp
+Examples:
+.D1 \&.Ic hash
+.D1 \&.Ic alias
+.Pp
+Note that using
+.Sx \&Bd Fl literal
+or
+.Sx \&D1
+is preferred for displaying code; the

+.Ss \&In

+.Ss \&It
+A list item.
+The syntax of this macro depends on the list type.
+.Pp
+Lists

+have the following syntax:
+.Pp
+.D1 Pf \. Sx \&It Cm args
+.Pp

+.D1 Pf \. Sx \&It
+.Pp
+with subsequent lines interpreted within the scope of the
+.Sx \&It
+until either a closing
+.Sx \&El
+or another
+.Sx \&It .
+.Pp
+The
+.Fl tag
+list has the following syntax:
+.Pp
+.D1 Pf \. Sx \&It Op Cm args
+.Pp
+Subsequent lines are interpreted as with
+.Fl bullet
+and family.
+The line arguments correspond to the list's left-hand side; body
+arguments correspond to the list's contents.
+.Pp
+The
+.Fl column
+list is the most complicated.
+Its syntax is as follows:
+.Pp
+.D1 Pf \. Sx \&It Op Cm args
+.Pp
+The
+.Cm args
+are phrases, a mix of macros and text corresponding to a line column,
+delimited by tabs or the special
+.Sq \&Ta
+pseudo-macro.
+Lines subsequent the
+.Sx \&It
+are interpreted within the scope of the last phrase.
+Calling the pseudo-macro
+.Sq \&Ta
+will open a new phrase scope (this must occur on a macro line to be
+interpreted as a macro).
+Note that the tab phrase delimiter may only be used within the
+.Sx \&It
+line itself.
+Subsequent this, only the
+.Sq \&Ta
+pseudo-macro may be used to delimit phrases.
+Furthermore, note that quoted sections propagate over tab-delimited
+phrases on an
+.Sx \&It ,
+for example,
+.Pp
+.D1 .It \(dqcol1 ; <TAB> col2 ;\(dq \&;
+.Pp
+will preserve the semicolon whitespace except for the last.
+.Pp
+See also
+.Sx \&Bl .
+.Ss \&Lb
+Specify a library.
+The syntax is as follows:
+.Pp
+.D1 Pf \. Sx \&Lb Cm library
+.Pp
+The
+.Cm library
+parameter may be a system library, such as
+.Cm libz
+or
+.Cm libpam ,
+in which case a small library description is printed next to the linker
+invocation; or a custom library, in which case the library name is
+printed in quotes.
+This is most commonly used in the
+.Em SYNOPSIS
+section as described in
+.Sx MANUAL STRUCTURE .
+.Pp
+Examples:
+.D1 \&.Lb libz
+.D1 \&.Lb mdoc
+.Ss \&Li
+Denotes text that should be in a literal font mode.

+.Ss \&Nd

+macro.
+.Pp
+Examples:

+.D1 \&.Sx \&Nd format and display UNIX manuals
+.Pp
+The
+.Sx \&Nd
+macro technically accepts child macros and terminates with a subsequent
+.Sx \&Sh
+invocation.
+Do not assume this behaviour: some
+.Xr whatis 1
+database generators are not smart enough to parse more than the line
+arguments and will display macros verbatim.
+.Pp
+See also
+.Sx \&Nm .
+.Ss \&Nm
+The name of the manual page, or \(em in particular in section 1, 6,
+and 8 pages \(em of an additional command or feature documented in
+the manual page.
+When first invoked, the

+macro expects a single argument, the name of the manual page.
+Usually, the first invocation happens in the
+.Em NAME
+section of the page.
+The specified name will be remembered and used whenever the macro is
+called again without arguments later in the page.
+The
+.Sx \&Nm
+macro uses
+.Sx Block full-implicit

+.Em SYNOPSIS
+section; otherwise, it uses ordinary
+.Sx In-line
+semantics.
